Finding the Meaning of a Word Can Be Its Own Reward

You’re reading a book and come across a word you don’t know. You keep going, and a few lines later, it clicks. You realise what the word must mean. There’s a small, satisfying moment of clarity—an "aha" moment. Our research suggests that this pleasant feeling may be part of the mechanism that makes learning work.

It would be impossible to learn all the words we know from direct instruction. Rather, one way we learn new words is through its context. We hear a new word in conversation, or encounter it in a sentence, and gradually infer its meaning. It’s an everyday process, so familiar that we rarely stop to think about how we do it at all. Why persist with something uncertain, without feedback or reward? One possibility is that the act of figuring things out is, in itself, rewarding.

In recent work, we tested this idea by asking people to learn the meanings of new words from context. Some words appeared in sentences that made their meaning clear; others did not. After each attempt, participants rated how much they enjoyed the experience. A day later, we tested what they remembered. The pattern was striking. When people successfully worked out a word’s meaning, they reported greater enjoyment. And crucially, that enjoyment predicted memory. Words that felt more enjoyable to learn were more likely to be remembered the next day.

Although previous studies have showed this effect for reading, we found that it wasn’t limited to reading alone. The same pattern emerged when people listened to sentences, or both read and listened at the same time. In other words, the reward didn’t seem to come from the format of the information, but from the moment of understanding itself. This indicates that we would experience the same effect from audiobooks, podcasts, and even conversations.

This fits with a broader idea in cognitive neuroscience: that learning and reward are tightly linked. When we experience a sense of insight, or an “aha” moment, brain systems involved in reward and memory interact. This seems to not just give us a sense of satisfaction, but also better memory.

Crucially, this kind of reward is intrinsic. It doesn’t depend on praise, points, or external incentives. It arises from information gain, or the sense that something has been understood that wasn’t understood before.

That has important implications for how we think about learning. We often assume that motivation must be added from the outside: through rewards, feedback, or pressure. But if learning itself can generate its own reward, then we need to ask how to create conditions in which learning feels meaningful, engaging, and worth the effort.

It also raises a more difficult question. If successful learning feels rewarding, what happens when it doesn’t? For some learners, particularly those with language or reading difficulties, these moments of clarity may be harder to come by. Learning may feel effortful without being rewarding, which could help explain why it is sometimes avoided.

Seen this way, motivation is not just a matter of willing ourselves to keep going. It may be rooted in whether the learning process itself delivers the kinds of experiences that reinforce it.
